itthaṁ yaśodā tam aśeṣa-śekharaṁ
 matvā sutaṁ sneha-nibaddha-dhīr nṛpa
haste gṛhītvā saha-rāmam acyutaṁ
 nītvā sva-vāṭaṁ kṛtavaty athodayam
ittham — in this way; yaśodā — mother Yaśodā; tam aśeṣa-śekharam — unto Kṛṣṇa, who was on the peak of everything auspicious, with no question of dirtiness or uncleanliness; matvā — considering; sutam — as her son; sneha-nibaddha-dhīḥ — because of an intense spirit of love; nṛpa — O King (Mahārāja Parīkṣit); haste — in the hand; gṛhītvā — taking; saha-rāmam — with Balarāma; acyutam — Kṛṣṇa, the infallible; nītvā — bringing; sva-vāṭam — at home; kṛtavatī — performed; atha — now; udayam — brilliancy by bathing Him, dressing Him and decorating Him with ornaments.
My dear Mahārāja Parīkṣit, because of intense love and affection, mother Yaśodā, Kṛṣṇa’s mother, considered Kṛṣṇa, who was at the peak of all opulences, to be her own son. Thus she took Kṛṣṇa by the hand, along with Balarāma, and brought Them home, where she performed her duties by fully bathing Them, dressing Them and feeding Them.

Kṛṣṇa is always neat, clean and opulent and does not need to be washed, bathed or dressed, yet mother Yaśodā, because of affection, considered Him her ordinary child and did her duties to keep her son brilliant.
